Blacklists Compared

18 October 2003

Survey results for all known public IP-based DNS blacklists.
Lookups were done on connecting IP addresses. The "union of most
IP zones" line excludes the query.bondedsender.org
zone because it is not a blacklist, and because they are too
aggressive to be widely useful the xbl.selwerd.cx
and block.blars.org zones are also excluded.
